Five top tips for Android 5.0 Lollipop

Here's how to get more out of the latest version of Android.

1. Use improved Face Lock
News flash: The Face Lock recognition feature on Lollipop actually works -- you can unlock your device by having it look at you. To use it, go to Settings-->Security-->Smart Lock-->Trusted Face. (Note that in order to Trusted Face to appear, you'll have to have already enabled the Screen Lock setting.) Go through the prompts for having it recognize your face. From then on in, it should work fine.

2. Use your phone as a flashlight
Want to use your device as a flashlight? No need to get a separate app for it -- it's built right into Lollipop. Swipe down from the top of the screen to open Quick Settings, then tap the Flashlight icon. (Note that this icon won't appear on all devices.)

3. Pin an app for safe device sharing
Worried that if you let someone use your Android device, they may find their way into private information, or else harm the device in some way? There's a new feature that lets you share safely -- pin an app so that someone can use only that app and nothing else without knowing your password. Go to Settings-->Security-->Screen pinning. Turn Screen pinning on, then open the app you want "pinned," press the Overview button, and touch the pin icon. That's the only app that can be used without knowing your password. To unpin the app, long-press the Overview and back buttons at the same time.

4. Play the hidden flappy Android game
There's a hidden Easter Egg in Android 5.0 --- the flappy Android game. To play it, go to Settings-->About phone/tablet-->Android version. Then tap the Android version a number of times until the screen changes to a Lollipop screen. Tap the screen multiple times, then press and hold the Lollipop wording and after a while, the game appears. Tap the screen and you launch a small Android robot. You'll need to manouver it between the passing lollipops. It's a lot harder than you might think.

5. Use priority notification mode
Tired of constant notifications disturbing you, but still want to be alerted when there's a high-priority notification? You can use priority notification mode. Press the up volume or down volume key, and on the screen that appears, tap Priority. Then tap Indefinitely if you want the mode turned on until you manually turn it back off, or else tap the button below it to set the amount of time you want priority notification mode to be turned on.

Full speed ahead for 802.11ac Gigabit Wi-Fi

802.11n takes a back seat as Wave 1 and 2 802.11ac wireless LAN products drive rollouts

Last December customers were peppering wireless LAN vendors with questions about whether to upgrade to the pre-standard-but-certified 802.11ac products flooding the market or hold off until 2015, when more powerful “Wave 2” Gigabit Wifi gear was expected to become prevalent.

A year later, even though Wave 2 products have begun trickling into the market, many IT shops seem less preoccupied with Wave 2 and more focused on installing the Wave 1 11ac routers, access points and other products at hand. After all, this first wave of 11ac is at least a couple times faster than last generation 11n, plus has more range, boasts better power efficiency and is more secure. And even Apple’s new iPhone 6 and 6 Plus support it.

Surprisingly, 802.11ac products aren’t much more expensive than 11n ones, if at all. That might help explain why market watcher Infonetics reported in September that “802.11ac access point penetration has nearly doubled every quarter and is starting to cannibalize 802.11n.” And the company is optimistic that 11ac and Wave 2 products, plus carrier interest in the technology, will give the WLAN market a boost in 2015.

Ruckus Wireless, which sells WLAN gear to enterprises and carriers, sees customers taking a middle-of-the-road approach, buying some 11ac products now and figuring to buy more when Wave 2 products are plentiful. Ruckus is looking to let customers who do invest in 11ac now upgrade products to Wave 2 at little to no cost down the road.

Aruba Networks, which rolled out 802.11ac access points in May of 2013 to deliver more than 1Gbps throughput, is now shipping more 11ac than 11n gear.

“We’re definitely seeing customers making the shift -- almost all of them are either actively looking at ‘ac’ or are starting to think about it in the next year,” says Christian Gilby, director of enterprise product marketing and owner of the @get11ac Twitter handle. “What’s really driving it is the explosion of devices. From a standards point of view, there are [more than 870] devices WiFi Alliance-certified for ‘ac’.”

Many of those devices were certified before the standard was finalized and do not support the performance-enhancing options that so-called Wave 2 products will feature. This includes support for multi-user MIMO, which allows transmission of multiple spatial streams to multiple clients at the same time. It’s seen as being akin to the transition from shared to switched Ethernet.

Wave 2 chipsets and gear have begun trickling out, with Qualcomm being among the latest. But WiFi Alliance certification could still be quite a few months away – maybe even into 2016 -- and that could make buyers expecting interoperability hesitate.

The real holdup for Wave 2, though, says Gilby, is that it will require a chipset change

in client devices such as laptops and tablets. “You really need the bulk of the clients to get upgraded before you see the benefits,” he says. (A recently released survey commissioned by network and application monitoring and analysis company WildPackets echoed Gilby’s sentiments and found that 41% of those surveyed said that less than 10% of their organization’s client devices supported 11ac.)
I think we’ll see some enterprise products on the AP side in 2015…in fact, I’m pretty sure we will."

Christian Gilby, director of enterprise product marketing, Aruba Networks
Gilby adds that while Wave 2 products will support double the wireless channel width, the government will first need to free up more frequencies to exploit this. Customers will also need to make Ethernet switch upgrades on the back-end to handle the higher speeds on the wireless side, and new 2.5Gbps and 5Gbps standards are in the works.

Nevertheless it sounds as though enterprise Wave 2 802.11ac products will start spilling forth next year, with high-density applications expected to be the initial use for them. “There’s been some stuff on the consumer side… I think we’ll see some enterprise products on the AP side in 2015…in fact, I’m pretty sure we will,” said Gilby.

Ruckus Wireless vows to become one of the first vendors to market with a Wave 2 product in 2015 and has already had success with it in the labs using Qualcomm chips, says VP of Corporate Marketing David Callisch. Though he says vendors will really need to work hard on their antenna structures to make Wave 2 work well. “As the WiFi standards become more complex, having more sophisticated RF control is beneficial, especially when you’re talking about having so many streams and wider channels.” He says that “11ac is where it’s at… Customers need the density. WiFi isn’t about the coverage anymore, it’s about capacity.”

Like Gilby, Callisch says the big hold-up with 11ac Wave 2 advancing is on the client side, where vendors are always looking to squeeze costs. Wave 2 is backwards compatible with existing clients, but still…

“It’s expensive to put ‘ac’ into clients,” he says. “If you adopted Wave 2 products today you really couldn’t get what you need to take full advantage of it. But that will change and pretty quickly.”

RELATED: Just another Wacky Week in Wi-Fi
As for how customers are using 11ac now, Gilby says where they have already installed 11n products on the 5GHz band, they are starting to do AP-for-AP swap-outs. It can be trickier for those looking to move from 2.4GHz 11n set-ups.
Aruba Series 200 802.11ac APs Aruba Networks

Aruba Series 200 802.11ac APs
802.11ac is also catching on among small and midsize organizations, which companies such as Aruba (with its 200 series APs) have started to target more aggressively. Many of these outfits opt for controller-less networks, with the option of upgrading to controllers down the road if their businesses grow.

It’s not too soon to look beyond 11ac, either. The IEEE approved the 802.11ad (WiGig) standard back in early 2013 for high-speed networking in the unlicensed 60GHz radio spectrum band, and the WiFi Alliance will likely be establishing a certification program for this within the next year or so.

Aruba’s Dorothy Stanley, head of standards strategy, says 11ad is “not really about replacing the W-Fi infrastructure, but augmenting it for certain apps.”

She says it could have peer-to-peer uses, and cites frequently-talked about scenarios such as downloading a movie or uploading photos at an airport kiosk. These are applications that would require only short-range connections but involve heavy data exchanges.

Stanley adds that developing and manufacturing 11ad products has its challenges. Nevertheless, big vendors such as Cisco and Qualcomm (via its Wilocity buyout) have pledged support for the technology.

“It’s something everybody is looking at and trying to understand where its sweet spot is,” Stanley says. “The promise of it is additional spectrum for wireless communications.”

Another IEEE standards effort dubbed 802.11ax is the most likely successor to 11ac, and has a focus on physical and media-access layer techniques that will result in higher efficiency in wireless communications.

A guide to the top mobile payments options

The launch of Apple Pay last month jump-started the mobile payments business, with several companies pushing hard to become your preferred payment method in stores. Even more competitors are on the horizon, promising to bring a lot more security and convenience compared to today's plastic payment cards.

The magnetic-stripe cards currently used in the U.S. are simply not very secure. Your name, card number and expiration date are all encoded on the stripe without protection, and hackers have been targeting payment terminals to steal that data, jeopardizing the security of tens of millions of card holders.

Banks are racing to introduce more secure, chip-based cards by October 2015, but phone-based systems like Apple Pay and Google Wallet are here now and offer a good deal of convenience and security. But not all mobile payment systems are equal. Here's a look at the major systems out there and how they work:

Apple Pay
Included with the iPhone 6, iPhone 6 Plus and upcoming Apple Watch, Apple Pay allows users to load their credit card details and then make payments using a short-range wireless system called NFC. With it, users simply bring their phones close to a terminal for a payment to be made. It's more secure too, because the card number isn't sent. Instead, a substitute called a token is sent so the retailer never sees your card number. The token, if stolen, is useless for subsequent purchases and the only time it gets matched to your card number is by your bank.

Apple has created a system that's incredibly easy to use: the cardholder authenticates the transaction by putting their thumb on the phone's fingerprint sensor, which happens in seconds. It only works with banks and card companies that have partnered with Apple, but that list is growing. Apple is keen to point out that it never sees details of your purchases. Only U.S.-issued cards are supported at launch, but it will expand to other countries in 2015.

Google Wallet
Also based on wireless NFC technology, Google Wallet appears similar to Apple Pay, but it's a little different behind the scenes. When paying with Google Wallet, Google assigns your phone a MasterCard number. It exists only in your phone -- you don't receive an actual card, and you don't have to go through a credit check. When you pay, the retailer gets that MasterCard number and Google immediately charges your chosen credit or debit card for the same amount. The two-step process, which is invisible to the user, means any U.S. debit or credit card can work with Google Wallet. It also means the retailer never sees your actual card number, which makes it more secure, but also means that Google can see every purchase you make.

Softcard
Backed by AT&T, Verizon and T-Mobile, Softcard is another NFC-based payment system. The service requires a dedicated Softcard app, customized by each carrier, and a special SIM card that has a secure payment chip. The SIM card is available free. It works with phones running Android 4.4 (KitKat) or above and Windows Phone 8.1 and supports cards from American Express, Chase and Wells Fargo. For other banks, Softcard will set up a virtual American Express card that can be used in much the same way Google Wallet uses a virtual Mastercard. With that, any debit or credit card is supported.

PayPal
The eBay-owned payments company is pushing beyond the virtual world into brick-and-mortar retail. One version, in use at Home Depot, allows PayPal account holders to purchase goods by tapping in their phone number and a PIN code at payment terminals. A newer version involves the customer "checking in" on a PayPal app when they enter a store that accepts the payment system. That action alerts the store to your presence and paying is as simple as telling the cashier you want to use PayPal. The check-in action transmitted your presence and account details to the store, so the cashier just needs match the charge to your account. The app is available on Android, Apple and Windows Phone.

CurrentC
CurrentC (get it? "currency") has been developed by some of the biggest names in retail in the U.S. including Sears, Target and Wal-Mart. It will be launched in early 2015 and, while many details are still unclear, appears designed to solve two problems for its backers. The first is the roughly 2 percent fee that credit card companies charge on each transaction. CurrentC will work with a customer's bank account, avoiding the fees although also losing the fraud protection offered on cards. Secondly, customers will be able to share personal information, like their name, birthday and contact details, with a store, presumably for incentives although quite how that will work is yet to be detailed.

A big difference lies in the technology used by CurrentC. Unlike Apple Pay, Google Wallet and Softcard, it doesn't use NFC but instead displays a barcode on a phone screen that is scanned by the cashier.

The system was under the radar until October when two CurrentC members, CVS and RiteAid, stopped accepting NFC payments right after the launch of Apple Pay. That brought a wave of negative publicity and eventually forced the company to divulge a little more about its plans. The CEO said additional forms of payment, including cards, might be supported and CurrentC could switch from a barcode to NFC or Bluetooth. But for now, we're just waiting to see what the retailers will come up with when it launches.

Cisco patches serious vulnerabilities in small business RV Series routers

The flaws allow attackers to execute commands, overwrite files and launch CSRF attacks

Cisco Systems released patches for its small business RV Series routers and firewalls to address vulnerabilities that could allow attackers to execute arbitrary commands and overwrite files on the vulnerable devices.

The affected products are Cisco RV120W Wireless-N VPN Firewall, Cisco RV180 VPN Router, Cisco RV180W Wireless-N Multifunction VPN Router, and Cisco RV220W Wireless Network Security Firewall. However, firmware updates have been released only for the first three models, while the fixes for Cisco RV220W are expected later this month.

ALSO: Celebrating 25 years of Cisco Networkers

One of the patched flaws allows an attacker to execute arbitrary commands as root -- the highest privileged account -- through the network diagnostics page in a device's Web-based administration interface. The flaw stems from improper input validation in a form field that's supposed to only allow the PING command. Its exploitation requires an authenticated session to the router interface.

A second vulnerability allows attackers to execute cross-site request forgery (CSRF) attacks against users who are already authenticated on the devices. Attackers can piggyback on their authenticated browser sessions to perform unauthorized actions if they can trick those users to click on specially crafted links.

This vulnerability also provides a way to remotely exploit the first flaw. Researchers from Dutch security firm Securify, who found both issues, published a proof-of-concept URL that leverages the CSRF flaw to inject a command through the first vulnerability that adds a rogue administrator account on the targeted device.

A third security flaw that was patched by Cisco allows an unauthenticated attacker to upload files to arbitrary locations on a vulnerable device using root privileges. Existing files will be overwritten, the Securify researchers said.

Cisco released firmware versions 1.0.4.14 for the RV180 and RV180W models and firmware version 1.0.5.9 for the RV120W.

Users can limit the exposure of their devices to these flaws by not allowing remote access from the Internet to their administrative interfaces. If remote management is required, the Web Access configuration screen on the devices can be used to restrict access only to specific IP addresses, Cisco said in its advisory.

10 Tools That Will Make You a Social Media Guru

These 10 tools will help you manage your individual or business social media accounts without breaking the bank.

10 Tools That Will Make You a Social Media Guru
Do you aspire to be a social media guru but find yourself befuddled by the large number of social media tools available? Here we help you narrow the options for managing your social media accounts by identifying 10 of the best online tools. All are either free or available for a reasonable subscription fee that any individual or a small business can afford.

Bitly
Bitly, probably the best-known UR- shortening service around, helps keep the links that you post on your social media accounts neat and tidy. Under the hood, the service features real-time analytics so you can track actual clicks. More importantly, the service supports the use of one custom domain name for free and implements all the necessary logic. You can brand your shortened URL the same way the big-time players do, like nyti.ms (The New York Times) and econ.st (The Economist).

Buffer
Buffer ranks among the most popular social media message scheduling service available. You can share content and schedule posts across Twitter, Facebook, LinkedIn and Google+ pages with a single click. The service makes it possible to stagger content throughout the day, constantly populating your social media feeds with new updates. Buffer also offers analytics about the reach of your posts and makes it easy to re-post popular content.

Hootsuite
Hootsuite is an advanced social media management dashboard designed to help organizations or power users manage multiple social media accounts. The online service works with Twitter, Facebook, LinkedIn, Google+ pages and other popular social networks. It offers a comprehensive range of reports that let you gain greater insights into ongoing social campaigns. Hootsuite starts off as a free service for individuals; various subscription tiers are available for power or business users.

Pagemodo
The Pagemodo social marketing suite can help small businesses quickly create engaging visuals for Facebook. Its features include tools to manage Facebook pages and to create customized, eye-catching cover photos, visual posts and even custom tabs for contests. New posts go live immediately or according to a schedule, and they can be shared on Facebook, Twitter, LinkedIn and other platforms.

The Social Mention real-time social media search and analysis tool scrapes user-generated content across more than 100 social media sites for mentions of a given company name, brand, product or search term. Considered among the best free listening tools on the market, Social Mention's analyses delivers relevant results, with metrics that includes unique authors, reach, frequency of mentions and top keywords.

SocialBro
SocialBro helps businesses better target and engage with their Twitter audience. It can analyze followers' timelines of followers to generate reports (such as the optimal time to tweet for reach and engagements), to identify key influencers and competitors, and to gain general analytics insights. SocialBro works best when coupled with a scheduling tool such as Buffer or Hootsuite. It's free with basic features for accounts with less than 5,000 Twitter followers.

SocialOomph
The SocialOomph Web service offers a long list of productivity enhancements across supported services. That list includes Facebook, Twitter, LinkedIn and Plurk, as well as blogs built with WordPress, Blogger, Tumblr and Moveable Type. Available for free with some basic features, the paid version of SocialOomph can schedule Facebook updates and LinkedIn shares, automatically follow back followers, search for worthwhile Twitter friends to follow and even tweet via email.

Sprout Social
The Sprout Social management and engagement tool can post, monitor and analyze multiple social media accounts from one location. The service offers the ability to monitor messages across Facebook, Twitter, Google+ and LinkedIn personal profiles, all through a single inbox. A paid service that comes with a free 30-day trial, Sprout Social also offers real-time brand monitoring and comprehensive reporting tools to help users understand important metrics.

Tweepi
The Twitter-only management tool Tweepi makes it easy to identify (and get rid of) followers who unfollow and inactive users, as well as to find interesting new users by scraping the followers of specified Twitter accounts. The paid version offers smart shortcuts that let users quickly follow or unfollow large number of users at a time. It ranks among the more powerful tool for managing Twitter accounts with thousands of followers.

TweetDeck
As its name suggests, the free TweetDeck (now owned by Twitter) is a Web and desktop solution for monitoring and managing Twitter feeds on a single screen. TweetDeck incorporates powerful filters based on specific keywords or conditions. It also offers the flexibility to customize the display to show or hide columns to better focus on what matters. TweetDeck is available for the Chrome, Firefox, Internet Explorer and Safari browsers, as well as Windows and Mac computers.

Virtual reality gains a small foothold in the enterprise

Prototypes and simulations based on virtual reality can save companies millions.

The rapid growth of the mobile sector has had an unexpected dividend – by bringing down the costs and improving the quality of motion sensors, screens, and processors it has helped usher in a new era of virtual reality technology.

Systems previously available only to largest manufacturers or to the military can now be put together with consumer-grade technology at a fraction of the price, and companies are already taking advantage of the opportunities.

When it comes to virtual reality, one of the biggest bangs for the buck is in virtual prototypes. Virtual models of buildings, oil tankers, factory floors, store shelves or cars can now be uploaded into a virtual environment and examined by safety inspectors, designers, engineers, customers and other stakeholders.

The Ford Motor Company, for example, has long been using virtual reality when it comes to prototypes and simulations, but the new wave of virtual reality technology is dramatically expanding its reach.

Ford's Immersive Virtual Environment lab, one of several areas in which Ford uses virtual reality, for example, has recently added the Oculus Rift virtual reality headset to its virtual reality platforms.

It's used in combination with a shell of a car where the seat, steering wheel, and other parts can be repositioned to match those of a prototype car.

“If you look at it, you'd think it was a very stripped-down vehicle,” says Elizabeth Baron, who heads up the lab. But when engineers sit down in the driver's seat and put on virtual reality headsets, they're virtually transported into the interior of the prototype.

Elizabeth Baron shows how Ford uses Oculus Rift.

“You have a gas pedal, brakes, steering wheel, a door, and when you're touching stuff, it's real,” Baron says. “But when you're looking around, you're seeing the virtual data. That's where the Oculus is specially useful.”

The Oculus Rift is the head-mounted virtual reality display that ushered in the current age of virtual reality with a $2.4 million Kickstarter campaign in 2012, followed by a jaw-dropping $2 billion buyout by Facebook earlier this year.

The Oculus Rift hasn't officially hit the market yet, but developer kits are available from the company for $350 each and more than 100,000 have already been sold. The device combines a high-resolution screen, motion sensors, and a set of lenses. The motion sensors track where the user is looking and the lenses stretch out the screen so it covers most of the user's field of view. The result is a very convincing illusion that the wearer has been transported into a virtual world.

“I'm extremely excited about the developments in the headspace scene and the work Oculus has done to bring low cost, wide-field of view to the market,” Baron says. “I'm just over the moon about it. The good thing for Ford is, with our approach for using different display technologies, we're already ready to take advantage of the developments that come out of the virtual headset space.”

Another virtual reality system is a CAVE (computer assisted virtual environment), which is a room with large screens on three walls and on the ceiling. Users wear stereoscopic glasses for a holodeck-like effect – life-size, 3D images of objects appear in the middle of the room, so that engineers can walk around and examine them.

Another system allows users to walk around inside a large open space while it tracks their position. “We can put an F-250 [super duty truck] into that environment and you can walk around it like it's a life-sized vehicle,” Baron says. “It's like an inspection tool for what we're producing and what our customers might take delivery of. That's a really important aspect in our product development process.”

A virtual environment allows engineers to dial up different lighting settings, to see how the exterior would look at noon on a hazy day, or in the evening or under mercury vapor lights. Virtual environments also help enable long-distance collaboration, she says.

“We also have a virtual space in Australia, and if they're immersed and we're immersed at the same time, we can see where they are in the virtual environment and we can talk to each other,” she says. “We can say, 'Look at this, look at that.'”

And virtual reality allows the company to look at many more prototypes than would have been possible if they had to be actually built.

“There is no way we could build thousands of prototypes,” she says. “We would only be able to build a handful. But also, there is no way we could check in the physical world all the things we check in the virtual worlds. We can make intelligent decisions about our design, with respect to how we manufacture it, and that's a huge time save and cost save.”

Ford is expanding its use of virtual reality, she adds. “We're actually creating another virtual space here in Dearborn [Michigan] to handle the overflow,” she says. “We're so packed. We can't fit in what we can do in one day. It's been shown to be so valuable.”

Ford also uses virtual reality for manufacturing assembly simulations, to help ensure the health and safety of workers, for training, and to study how drivers behave.

“We have driving simulations, another virtual reality application, where we'll bring in people who haven't slept all night and ask them to perform some tasks,” she says. “And then perform an analysis on how they respond versus someone who's had their fresh cup of coffee and they're bright and cheerful in the morning.”

Other manufacturing companies are also upgrading their virtual prototypes from simple 3D graphics on a monitor to fully immersive virtual reality systems such as those made possible by the Oculus Rift and similar devices.

Medical device companies, for example, are among the early adopters, says Jeremy Duimstra, a professor of user experience at University of California San Diego and CEO and creative director at San Diego-based MJD Interactive, which counts Disney, Red Bull, P&G and Titleist among its clients.

“Being able to virtually interact with a device in the design phase, without having to build physical objects ... allows for more innovation,” he says.

Plus, there's the cost savings of materials and manpower of physically mocking up hundreds of prototypes. “Build the product virtually, test it, iterate, and only build when you know it's right,” he says.

Jeremy Duimstra
Environments that are physically dangerous for people are also ripe for going virtual.

“Our oil and gas clients are definitely interested in this space,” says Mary Hamilton, who heads up the digital experiences research and development group at Accenture. Immersive virtual reality allows people who might be in different locations to visit a difficult-to-reach facility, to get views such as X-rays or schematic views that might be impossible in real life, and enables low-risk, lower-cost training for new employees.

Marketing applications are also expanding, she says.
For example, low-cost head-mounted displays will allow retailers to replace their immersive CAVE environments – which can cost hundreds of thousands of dollars to set up. Companies can use the technology to have focus groups walk through virtual stores, interact with different shelf layouts, or even try out new products.

“It would significantly lower costs, allow companies to do more of this, and allow them to do it in multiple locations,” she says.

The second wave
One virtual reality wave has already come and gone, in the 1990s. Movies like “The Lawnmower Man,” devices like Nintendo's Virtual Boy and virtual reality arcades made the technology hot, but by the time “The Matrix” came out at the end of the decade it was clear that virtual reality technology was too expensive and too bulky for widespread use. In addition, graphics quality was poor and high latency and poor head-tracking combined to make users nauseous.

As a result, virtual reality became limited to high-end, narrowly focused applications such as military simulations, movie special effects, and training and simulations in manufacturing, oil, and the medical industries, says Jacquelyn Ford Morie, formerly a virtual reality expert at the University of Southern California's Institute for Creative Technologies. Virtual reality immersion therapy has been used for a decade now to treat Post Traumatic Stress Disorder, and to manage the pain of burn victims.

“Now we have this second wave of virtual reality,” says Morie. “The difference between then and now is that it's affordable. Instead of a $30,000 head-mounted display, you now have a $300 head-mounted display.”

jacquelyn ford morie
Jacquelyn Ford Morie is founder and chief scientist at All These Worlds Inc., a Los Angeles-based virtual environment consulting and development firm.

The general population is also more used to technology than they were 20 years ago, she adds, and there are more companies creating content for the new virtual reality platforms. Her own company creates applications in virtual worlds for NASA and other enterprise clients.

“We're doing things like making virtual worlds that will help astronauts on long-duration space flight missions,” she says.

Today, most enterprise virtual reality is internally focused, she says. That is likely to change as more of this technology gets into the hands of consumers, and she's looking forward to working on consumer-focused projects.

“If everyone has a 3D head-mounted display, there's no reason not to feed a preview of that new product,” she says. “Create emotionally evocative, 3D immersive ads, so all of a sudden they feel like they're on the mountain, about to ski down with my new snowboard.”

YouTube served malicious ads

The ads redirected victims to the Sweet Orange exploit kit, which tries to install malware, Trend Micro says

Malicious advertisements, some of which were displayed on YouTube, redirected more than 113,000 people in the U.S. to harmful websites in just a month, Trend Micro said Tuesday.

Although online advertising companies try to detect and block such ads from being circulated on their networks, bad ones sometimes get through. Such ads can be very productive for hackers. It can mean a large pool of victims if shown on a high-traffic website.

"This was a worrying development: Not only were malicious ads showing up on YouTube, they were on videos with more than 11 million views -- in particular, a music video uploaded by a high-profile record label," wrote Joseph Chen, a fraud researcher, on Trend Micro's blog.

Google, which owns YouTube, did not have an immediate comment.

Chen wrote that users viewing the ads were bounced through two servers in the Netherlands before landing on the malicious server, which is located in the U.S.

That server had the Sweet Orange exploit kit installed. Sweet Orange checks if the computer has one of four vulnerabilities affecting Internet Explorer, Java or Adobe Systems' Flash application.

If the attack is successful, the kit delivers malware from the KOVTER family, which has been used in the past for ransomware, Chen wrote. Those attacks try to extort a victim by either encrypting their files or tricking them into paying a fine.

The KOVTER malware is hosted on a subdomain of a Polish government site that has been hacked, Chen wrote. The attackers had also modified DNS (Domain Name System) information on that site by adding subdomains that led to their own servers, but the method used to accomplish that was unclear, Chen wrote.

Cisco welcomes Dimension Data to global cloud initiative

The company compared its Intercloud to international roaming for hybrid clouds

The sun shone outside the Cisco Live conference on Tuesday even as the clouds gathered within, and that was exactly the kind of weather Cisco was hoping for.

Hosting and cloud provider Dimension Data signed on to use Cisco's Intercloud platform, Cisco executive Rob Lloyd announced in a keynote address that emphasized hybrid clouds and making IT infrastructure easier to set up and manage.

Cisco will sell cloud services using Dimension Data's Managed Cloud Platform, including IaaS (infrastructure-as-a-service) and SaaS (software-as-a-service) offerings of Microsoft SQL Server and SharePoint, said Lloyd, who is Cisco's president of development and sales. The services are available now through 10 Dimension data centers worldwide, which will expand to 13 by the end of September, according to Cisco.
MORE ON NETWORK WORLD: 15 more useful Cisco sites

The services coming through Dimension Data will be aimed at medium-sized enterprises and at smaller service providers that want to resell cloud services, especially in the developing world, Lloyd said.

Intercloud is Cisco's architecture for linking private and public infrastructure around the world into a single cloud. It will let enterprises and service providers host workloads anywhere and move them around based on regional needs and compliance requirements. Cisco is using Intercloud to offer its own services, backing away from earlier pledges not to compete with its service-provider customers, but is still counting on partners to bring their infrastructure to the party.

Australian carrier Telstra, a longtime Cisco customer, was the company's first announced Intercloud partner. Dimension Data, a Cisco partner for 23 years, and parent NTT have now joined in, Lloyd told Cisco Live attendees.

Lloyd compared the concept to international roaming on cellular networks.

"We're going to embrace all cloud partners ... in the countries where we do business around the world, and in partnership with our cloud partners," Lloyd said.

Hybrid clouds are the future because they combine the easy expansion possible on a public cloud and the security and control of private infrastructure, he said. Cisco's platform for building those clouds, and the foundation of Intercloud, is ACI (Application Centric Infrastructure).

This platform, Cisco's entry into the SDN (software-defined networking) sweepstakes, is designed to simplify network provisioning, management and teardown, and make infrastructure more secure. It works in conjunction with Cisco-designed silicon on the recently introduced Nexus 9000 switch, but its benefits have also been extended to much of the older Cisco gear, including the Catalyst 6000 series and Integrated Services Routers, the company says.

Cisco has a lot riding on ACI, which was announced less than a year ago, and it may take a while to get the mass of its customers on board. Two IT engineers attending Cisco Live, both from large U.S. retailers, said they were just learning about ACI for the first time. The technologies they're now looking to adopt -- converged network-computing-storage platforms for one, and VoIP for the other -- are far from the cutting edge of Cisco's agenda. Cisco says it has 1,000 customers in the pipeline to adopt the Nexus 9000 and ACI.

Amazing 12 tips to tune your Wi-Fi network

 Wi-Fi networks can be very tricky to properly design and configure, especially in the small, crowded 2.4 GHz frequency band. In addition to interference from neighboring wireless networks, capacity issues arise when there are a high number of users on the network or a high density in a certain area.

In the early days of Wi-Fi, there weren’t that many Wi-Fi users or devices in the world. Today, the situation is much different. Private offices and buildings that have a wireless network may provide access to one, two, or even more Wi-Fi devices per worker and then maybe provide access for guests as well. More and more people are looking for Wi-Fi connectivity, especially at public venues -- on their laptops, smartphones and tablets -- to help conserve cellular data usage.

1. Design for throughput and capacity
When there weren’t many Wi-Fi users, you could design wireless networks pretty much based on coverage. You could perform a RF site survey and find the optimum locations for access points to ensure they provided adequate coverage. Now you should also design for throughput and capacity.

When designing a wireless network you should evaluate the Wi-Fi client devices that will be using it and how they’ll utilize it. Then you can do some calculations to figure estimated throughput and access points needed to support them, while also accounting for future growth and changes.

With 802.11b/g/n in the 2.4GHz band, there are only three non-overlapping channels. Thus co-channel interference becomes an issue when you bunch more than three access points in close proximity. Ideally, you don’t want an access point to hear any other access point on the same or overlapping channel. Though the 802.11 standards have mechanisms in place to deal with interference like this, co-channel interference will decrease performance.

2. Think about airtime
In areas where there is a high density of Wi-Fi users, like in public venues, you may find that the three 2.4GHz channels aren’t enough. However before overlapping channels and causing co-channel interference there are some techniques you might be able to utilize to increase capacity with the access points you already have.

Remember, wireless networks are all about airtime. Wi-Fi clients must contend for airtime with the access points as only one device, whether an access point or client, can transmit at any one time on a given channel. The higher the throughput and speeds data is transferred, the less airtime that is required, and generally the more clients that can connect and utilize the wireless access.

There are many settings you can configure to help boost performance and trim airtime.

3. Utilize 5GHz band steering

To help alleviate the crowded 2.4 GHz band, try to get Wi-Fi users onto the larger, less congested 5GHz band. Consider using dual-band 802.11n or 802.11ac access points that support band steering. When supported and enabled on the access points, dual-band clients will be guided or forced onto 5GHz instead of just leaving it up to the user or device to decide which band to

Most access points implement this type of functionality by responding only to the probe and association requests in the 5-GHz band when it has seen the same client with a probe/association request in the 2.4-GHz band. Thus once the access point knows a client is dual-band capable, it only allows connections from the client in the 5-GHz band.

In the 5-GHz band you have many more channels, and more Wi-Fi devices these days are supporting this band. However, do understand that 5GHz generally has less range due to the higher frequency. Thus you may have to do more Wi-Fi surveying to design for good 5GHz coverage.

If 5-GHz coverage isn’t up to par, consider configuring any band steering thresholds supported by the access point. Some allow you to set a minimum signal level a client must have before band steering will be used or a number of missed probe/association requests to 5GHz from the client before allowing connections on 2.4GHz.

4. Only use WPA2 security
Although both WPA and WPA2 security versions will work with 802.11n and 802.11ac, the data rates are limited to 54Mbps with WPA. You should select WPA2 only for the security on the private SSID(s) to allow maximum throughput when using the newer wireless standards. Any legacy clients not supporting the newer security should be upgraded.

5. Limit the amount of virtual SSIDs
When creating additional SSIDs, keep in mind that each one increases the overall overhead of the wireless network. Each SSID will generate additional beacons, probes, and other management traffic, taking up more airtime, even if the SSID isn’t being used. So consider limiting the number of virtual wireless networks; perhaps one for private access and another for public access. If needed, you can further segregate private access levels via dynamic VLAN assignment using 802.1X authentication for instance.

6. Disable lower data rates
Consider disabling the lower data rates to force packets, including those for management, to be sent via higher data rates and to ensure clients connect at higher data rates. This also encourages clients to automatically roam to better access points quicker rather than staying connected to an access point until the last second like they may normally do.

If you still have legacy 802.11b clients on the network you should really consider upgrading/replacing them, but you could still disable the lowest data rates (1M, 2M, and 5.5Mbps) and leave the highest (11Mbps) enabled.

If you don’t have any 802.11b clients, consider disabling all data rates at and below 11Mbps.
You’ll likely still need to support 802.11g clients, but if your Wi-Fi coverage is good enough you may also be able to disable some of the lower 802.11g data rates: 12M, 18M, 24M, 36M, and 48Mbps.

7. Configure proper channel-widths
On access points that support channels larger than the legacy 20MHz, you likely want to disable the Auto 20/40 MHz selection for 2.4GHz and only use the 20-MHz channels. In this band, it’s only possible to have one non-overlapping 40-MHz-wide channel. Thus larger channels are only really useful for areas where only one access point or channel will be used, including any neighboring networks.
MORE ON NETWORK WORLD: How to use public Wi-Fi hotspots safely

For 5GHz, however, you may be able to use larger channel-widths since there is more frequency spectrum. Just ensure the bonded channels will not cause co-channel interference with yours or neighboring networks.

8. Transmission times

Shortening packet sizes or transmission times can help increase performance as well. Here are a few settings you may want to enable:

9. Limit broadcast traffic
Broadcast traffic can also slow down the overall throughput of a wireless network, thus consider these two techniques to decrease broadcast traffic:

Enable wireless client isolation to prevent Wi-Fi devices from broadcasting to each other, if the user-to-user communication isn’t required. The Wi-Fi devices will still be able to communicate to wired clients, but not directly with wireless clients.
Separate the LAN and WLAN broadcast domains to cut down on the amount of broadcast traffic on the WLAN side.

10. Adjust the beacon interval
As mentioned earlier, each access point will broadcast a beacon packet for each individual SSID, which contains the basic information about the wireless network. The default interval rate at which beacon packets are sent over the airwaves is usually 100ms.

Increasing the interval rate will decrease the amount of beacons and the airtime they take up, but that can also cause other unwanted side effects. Typically, the smaller the interval, the quicker the clients will connect to and roam between the access points. The bigger the interval, the longer it takes clients to connect/roam and the longer delay for clients sending/receiving data that have power save mode enabled.

11. Adjust the fragmentation and RTS thresholds
Lowering the fragmentation and Request to Send (RTS) thresholds can help increase performance on wireless networks with a large number (at least over 5%) of collisions and/or interference.

If it appears you have a hidden node issue where clients are far apart and can’t hear each other but both can hear the access point, then start with reducing the RTS threshold. Perhaps start with threshold of around 500 bytes.

If hidden nodes don’t appear to be an issue, start with reducing the fragmentation threshold. Perhaps start with threshold of around 1,000 bytes.

12. Additional site surveys
Keep in mind, reducing these thresholds can also slow the network if not truly needed. I recommend making slight changes and then performing testing to ensure you’re seeing an improvement.

In addition to tweaking these settings, you may want perform additional RF site surveys if capacity issues still arise. You may find adjusting access point transmit levels and the access point locations can help make cell sizes smaller, enabling you to put more access points into an area. Also look into other network configurations that could affect capacity, for instance an adequate DHCP range.

Four smartphone OSs fighting for survival

BlackBerry, Tizen, Ubuntu Touch and Firefox OS take different approaches to staying alive.

The smartphone operating system market is dominated by Android and iOS, but you can never count out Microsoft, so let’s say that Windows Phone, despite lagging in market share, rounds out the Big Three.

That leaves four other smartphone operating systems fighting for survival. The odds that any of them will threaten the market leaders are pretty slim, but the companies behind them are pressing on. They may be looking to gain a foothold selling cheap smartphones in so-called emerging markets; hedging against the control that Apple, Google and Microsoft are wielding; or simply figuring that they have nothing left to lose.

Here’s what the other four smartphone OSs have been up to lately and what their strategies for survival are.

1. BlackBerry: Cool to be square
BlackBerry OS is now in an epic struggle against Windows Phone for third place when it comes to U.S. market share, but, of course, BlackBerry has been on a long, downward slide. In 2009, Blackberry’s market share was north of 50%.

The BlackBerry company has refocused on selling their devices and services to their traditional business and government clientele, including launching an enterprise-secure messenger, BBM Protected, for the BlackBerry OS.

In June, BlackBerry announced that the Amazon Appstore would be included with BlackBerry 10.3 when the OS is released this fall. (BlackBerry 10 can already run most Android apps.) The company’s own app store, BlackBerry World, will remain active but has stopped selling movie, music and TV downloads.

As for hardware, an entry-level smartphone, the Z3, was released in late June (first in India and Indonesia). The BlackBerry Classic (coming possibly in November) will be an update of the familiar BlackBerry phone with a built-in physical keypad, while the BlackBerry Passport (September) -- which will also have a physical keypad -- will have a much larger and oddly square-shaped form factor.

In June, the company reported a profit in its first fiscal quarter, which is good news. The not-so-good news: Sales numbers of BlackBerry devices fell, which could lead to further eroding of BlackBerry OS’ market share. At this point, the Passport’s unique looks might help the OS itself stand out.

2. Firefox OS: Not available in the U.S. (except on eBay)
Firefox OS is an open-source mobile OS. It works similarly to the Android version of the Firefox browser; its apps are basically web apps. The first Firefox phone sold to the general public (as opposed to just developers), the Open, was launched last July. It remains only available in the U.S. on eBay. According to its maker, ZTE, the phone has sold more than 100,000 units worldwide, but several user reviews pointed to a buggy device prone to crashing.

Mozilla announced on June 10 the launch of a Firefox phone that might cost only $25. We’re nonplussed: The true expense of a phone lies in its hardware, not operating system. Obviously, to achieve this low price, the phone will have fewer features and with less performance power compared to most entry-level smartphones nowadays. And the plan is to sell this cheap phone in India and Indonesia first. (Prior Firefox phones have been available in Europe and Latin America.)

As for the U.S., Mozilla admitted last November the region is not their main focus for selling Firefox phones. Meanwhile, ZTE’s Open was followed by the Open C, which was released in May and is also only sold on eBay.


3. Tizen: Don’t go Russian out to buy one
Like Firefox OS, this mobile OS is open-source, but has had a long and convoluted history. All you need to know is its lineage is traced back to four separate OSs supported by multiple companies, but they eventually converged under the new name Tizen. Today, Intel and Samsung are its main backers. Samsung is using Tizen for its smart TVs and smartwatches. In fact, the Galaxy Gear smartwatch, which originally came with Android, had a software update issued at the end of May which entirely replaces this OS with Tizen.

Samsung also announced on June 3 the Samsung Z, their first smartphone to run Tizen. The company plans to release it during the third quarter of this year -- but first in Russia.

It’s unlikely the company will ditch Android anytime soon from its future mobile devices, though. It is pretty much the top Android device seller in the world. The company will still sell smartwatches that use the new version of Android designed for wearable devices, Android Wear.

4. Ubuntu Touch: Crowdfunding flop takes the Edge off
Last July, Canonical tried crowdfunding for the Ubuntu Edge, a smartphone that could also be used as a desktop PC when docked. They asked the public to pledge $32 million to put it into production, but raised only $12.8 million. It was speculated that the whole effort had really been a publicity stunt to draw attention to Canonical’s general goal to bring their Ubuntu OS to smartphones and tablets.

Since the Edge’s failure (or PR success), Canonical has managed to get two device companies on board to use the mobile version of their OS, Ubuntu Touch. In February, the company announced partnerships with Chinese phone maker Meizu and a Spanish one, bq; both will release Ubuntu phones for presumably Europe and Asia sometime later this year.
Ubuntu Edge

There was apparently some interest in the Edge, which would have had higher-end technical specs, but it’s expected that whatever phones Meizu and bq introduce could be technically mid-range. Like Mozilla, Canonical looks to be facing a formidable challenge getting companies to make smartphones running their OS over Android, even for lower-end models.

If you want to try Ubuntu Touch and own a Nexus 4, you can download and install it on your phone.

2014's Starting Salaries for College Tech Majors

As summer is winding down and colleges and university are about to kick it into high gear, it's time again for us to look at how college technology majors stack up in regards to starting salaries.

College Technology Major Starting Salary 2014
With two thirds of the summer behind us, it's the time of the year for students of all ages to contemplate what degree program to enroll in. And while compensation isn't always the biggest factor in their choice for a profession, it can be a good place to start.

Each year, with data provided by the National Association of Colleges and Employers (NACE), CIO.com looks at what degrees offer the best starting point salaries and how trends and markets have affected them over the previous years' data. Data in the Salary Survey is produced through a compilation of data from the BLS and the Census Bureau.

Average Salaries by Major
Salary gains are down significantly when compared to that of the previous salary survey. In fact, information sciences and systems degrees took a hit of almost 1%. This years' largest gain was in mechanical engineering degrees, up 2.5 percent, but that pales in comparison to the previous year's gains of 5.6 percent.

Computer Science Degree Starting Salaries
Under the computer science umbrella, federal, state and local government officials are still the head of the pack followed closely by the manufacturing industry. All players in this category made small gains.

Information Sciences and Systems Major Starting Salaries
Information sciences and systems saw graduates and entrants pretty flat over the last year. Federal, state and local government positions still are paying the highest in this category as well, beating out manufacturing by 9%. Professional scientific and technical services lost ground slightly on starting salary and the number of graduates decreased.

Computer Engineering Starting Salaries
Computer engineering degrees, in most cases, made modest gains. Professional, scientific, and technical services saw a 7% increase in pay over previous salary surveys. People with computer engineering degrees who chose enterprise management lost 3 % on starting salaries year over year.

Electrical/Electronics & Communications Engineering Degree Starting Salaries
If you've been paying attention, government jobs are where the money is at when you're just getting started with your technology degree, and it's no different with electrical/electronics and communications engineering degrees. No major gains made in this category over the last year and there were fewer graduates in the major categories.

Mechanical Engineering Degree Starting Salaries
Mechanical engineering graduates made significant increases in all areas except federal, state and local government positions. In the professional, scientific and technical services industries mechanical engineering graduates gained 12 percent year-over-year.

Tech Majors
There are many things to consider when choosing which technology degree is right for you, and starting salary is only one of them. Things like cost of living for a particular area, salaries levels for your region and personal interests all play a role. What is the most important factor to you? We'd love to hear from you in the comments.

For a look at last year's data, please check out my previous article, Best College Tech Majors for Landing a Top Starting Salary.

Google brings robust cluster scheduling to its cloud

Google is drawing from the work of the open-source community to offer its cloud customers a service to better manage their clusters of virtual servers.

On Monday, the Google Cloud Platform started offering the commercial version of the open-source Mesos cluster management software, offered by Mesosphere.

With the Mesosphere software, "You can create a truly multitenant cluster, and that drives up utilization and simplifies operations," said Florian Leibert, co-founder and CEO of Mesosphere. Leibert was also the engineering lead at Twitter who introduced Mesos to the social media company.
10 of the Most Useful Cloud Databases

First developed by the University of California, Berkeley, Mesos can be thought of as an operating system that allows an administrator to control an entire cluster of computers, or even an entire data center, as if it were a single machine.

Thanks to its fine-tuned scheduling capabilities, Mesos can allow multiple frameworks, such as Hadoop or Spark, to share a single cluster, as well as allow multiple copies of the same framework to run on a single cluster.

The software also has built-in resiliency: If one or several nodes stop working, the software can automatically move that work to other, operational nodes in that cluster.

Twitter, Airbnb, Netflix and Hubspot have all used Mesos to coordinate operations.

Google has modified its new software for managing Docker containers, called Kubernetes, so it can run on Mesos, work Google also announced Monday.

Google has been an ardent user of Docker internally, using more than 2 billion containers a week in its routine operations. The open-source Docker provides a container-based virtualization, which is an alternative to traditional virtualization workloads now being considered by many organizations, due to its putative performance superiority.

Now, Google customers can use Mesosphere cluster to run Docker containers and use any leftover capabilities to run other framework-based workloads.

"You'll be able to create these modern distributed systems the way that Google does, and you'll be able to run them side-by-side with all your existing applications," said Craig McLuckie, Google Cloud Platform product manager.

Users can also move their workloads to any cloud provider that runs Mesos, eliminating the dependencies that can come with writing the applications to run on a specific cloud service, be that Google's or some other vendor's.

Google's Mesosphere cluster package also includes the Apache Zookeeper configuration software, the Marathon scheduling software, as well as OpenVPN for logging into the cluster.

Use of Mesosphere on the Google Cloud Platform is not billed separately; it is included in the price of running a cluster.

Big tech firms back Wi-FAR for remote broadband

802.22 standard, approved in 2011, promises low-cost broadband for remote areas

Google, Microsoft and Facebook are cranking up an emerging wireless technology known as Wi-FAR to help reduce the digital divide in remote and unconnected regions of the world.

Wi-FAR is a recently trademarked name from the nonprofit WhiteSpace Alliance (WSA) that refers to the 802.22 wireless standard first approved by the IEEE (Institute of Electrical and Electronics Engineers) in 2011.

The standard shares the underused TV band of spectrum called whitespace to send wireless signals, typically over distances of six to 18 miles in rural and remote areas. It has a theoretical download speed of more than 22 Mbps per TV channel that serves up to 512 devices, according to the WSA. That could result in speeds of about 1.5 Mbps on a downlink to a single device.

While such speeds are far slower than for the gigabit fiber-optic cable services that Google and AT&T are building in some U.S. cities, the speeds could theoretically begin to compete with some 3G cellular speeds, although not 4G LTE speeds. For an impoverished or sparsely populated region where businesses and schoolchildren have little Internet access, Wi-FAR could be a godsend when used to link base stations (typically found at the ground level of cell towers) in a distributed network.

About 28 million people in the U.S. don't have access to broadband, while globally, about 5 billion people, nearly three-fourths of the world's population -- don't have broadband Internet access, said Apurva Mody, chairman of both the WSA and of the 802.22 Working Group.

"This is cheap Internet access and there are dozens of trials underway, with Google in South Africa, Microsoft in Tanzania and other continents, and even Facebook's interest," Mody said in an interview. "You have 1.2 billion people in India who need cost-effective Internet access. There's a lot of enthusiasm for Wi-FAR."

Wi-FAR will be cheaper for access to the Internet than LTE and other wireless services. The lower cost is partly because Wi-FAR works over unlicensed spectrum, similar to Wi-Fi, which allows network providers, and even government entities, to avoid paying licensing fees or needing to build as many expensive cell towers, that can cost $50,000 apiece, Mody said. "The prices for Wi-FAR service will be very small, perhaps less than $10 per month per household."

The 802.22 technology can be low cost because the whitespace spectrum is shared with conventional users, including TV stations on UHF and VHF bands. Thanks to sophisticated databases that track when a whitespace channel will be in use in a particular region, a cognitive (or smart) radio device can determine when to switch to another channel that's not in use. Testing in various Wi-FAR pilots projects, many of them in Africa, is designed to prove that Wi-FAR devices won't interfere with other existing users on the same channel.

"We have yet to have an interference problem," said James Carlson, CEO of Carlson Wireless Technologies, a Sunnyvale, California-based company that is working with Google on two six-month trials of 802.22 in the UK, among other areas. The company completed a successful trial with Google serving students in South Africa in 2013. Carlson, in an email interview, said the company is working with five database providers, noting that the "prime purpose of the database is to protect the incumbent spectrum user."

Whitespace spectrum sharing, coupled with the use of the databases, is generally called dynamic spectrum allocation technology. In January, the U.S. Federal Communications Commission approved Carlson's RuralConnect TV whitespace radio system for use with a Spectrum Bridge TV whitespace database, effectively bringing the first dynamic spectrum sharing product to market.

In the U.S., RuralConnect is authorized for use in the UHF TV band, running from 470 MHz to 698 MHz. The FCC opened up the band in 2010.

At the time, Carlson said the FCC's approval would give a boost to global efforts to use whitespace technology. "Providing connectivity to underserved populations worldwide is more than an interest to us," he said in a statement. "It's our corporate mission."

RuralConnect will get competition from products in other companies, including Redline, Adaptrum and 6Harmonics, Carlson said. In addition to other providers, Google has built a whitespace database that Carlson is testing.

In all, Carlson Wireless has piloted dozens of whitespace projects, and expects to start its largest yet for 30 base stations and 5,000 users near New Delhi in the next six months, Carlson said.

"India is the next big boom for online needs, and the rural areas are not getting [Internet service] with [typical] mobile systems," Carlson said. "So they are choosing to go with the TV whitespace because the UHF band is almost all vacant in rural areas and 600 MHz propagation is superb."

While Carlson has been working with Google, Microsoft separately announced in June a whitespace pilot project at the University of Limpopo in South Africa. It is part of a Microsoft 4Afrika Initiative to help ignite economic development in Africa.

In May, Microsoft and Facebook joined with SpectraLink Wireless to announce a whitespace project for students and faculty at universities in Koforidua, Ghana. That project brought the number of nations where Microsoft has whitespace pilots to 10 countries on four continents.

In the Microsoft and SpectraLink partnership, Facebook's Connectivity Lab team will lead efforts to better understand how TV whitespace spectrum can support wireless Internet users, according to a statement.

Microsoft and others believe that TV whitespace technology will best work in combination with Wi-Fi and other low-cost wireless technologies. While much of whitespace technology is focused on building specialized bridge hardware for use in base stations, Mody said some companies are developing fixed wireless 802.22 routers, similar in appearance to Wi-Fi routers, that will be placed inside of homes.

Microsoft also spearheaded the Dynamic Spectrum Alliance, which Google and Facebook joined last November. The alliance is exploring many uses for whitespace spectrum, including Internet of Things device connectivity.

Craig Mathias, an analyst and wireless consultant for The Farpoint Group, said 802.22 devices may compete against or complement a number of other technologies, including cellular and Wi-Fi.

"802.22 is not a pipe dream, but so far there's not a lot of evidence of its success," Mathias said in an interview. "It does make sense. The rate of innovation in wireless is so high that you hear something exciting every week. But not all wireless standards are successful in terms of having [successful] wireless products."

12 Tips to Help College Grads Land Their First IT Job

Technology and HR pros, as well as IT recruiters, share their advice on how recent graduates and those still in college can best position themselves for a technology career.

According to research conducted by labor market analytics and consulting firm Burning Glass , the future is looking bright, or brighter, for college students majoring in science, technology, engineering and math (STEM) -- especially if they are looking to go into healthcare, IT or engineering & advanced manufacturing. Indeed, according to Burning Glass's findings, STEM graduates have access to twice as many entry-level jobs as non-STEM graduates -- and the pay is better too, $66,123 compared to $52,299.

But just because you have a four-year degree in math or science or engineering does not mean you will get your dream job in IT, or any job in IT, or even a job interview.

So what can recent college graduates and students still in college do to boost their chances of getting their dream entry-level job in technology (be it at a software company, in healthcare or manufacturing/engineering)? Dozens of IT professionals, HR managers and recruiters offer their top 12 tips for how to increase the odds of landing your dream entry-level technology job.

1. Know what you are good at -- and if you want to be a specialist or a generalist, a technologist/coder or in product management or marketing. "Choose early on if you want to specialize in a certain segment, or if you want to be a generalist," says Evaldo Horn de Oliveira, director of Business Management, FairCom, a provider of database technology.

"If you are interested in management, then consider going the generalist route, since having diversified skills can help you land an entry-level position that will eventually lead you down the management track. It's also important to express your interest in management within an interview, which can alert the hiring manager that you are ambitious and have the drive to pursue opportunities for advancement," he says.

"Some technologists enjoy writing code. Others enjoy managing data centers. But there are also a host of roles like product manager, product marketing and even sales engineering that require passion and understanding of the technology but may play to additional nontechnical capabilities like communication skills and leadership," says Lilac Schoenbeck, vice president of product management and marketing, iland, an enterprise cloud infrastructure provider.

So before you start applying for jobs, she (and others) advise that you learn about the different options and career paths available and apply for positions best suited to your interests and talents.

2. Learn everything you can about the company and position you are applying/interviewing for, before you apply or interview there. "Familiarize yourself with the company," says Jennifer Rutt, senior director of Engagement, AfterCollege, a career network for college students and recent graduates.

"Have they been featured recently in the press? Are they active on TechCrunch?" Find out, Rutt says. Then, in your cover letter or during the interview, "highlight some of the exciting things the company is doing and why you would want to be engaged in that work and how you could add to the project with your skills."

"Inspire confidence by walking into the interview with a deep understanding of what the company sells," says Mindy Lieberman, vice president of IT at Zendesk, a provider of customer service software. "If it's an SaaS company, play with a free trial, if there is one. Also, "check out reviews [in tech publications], or find a friend who is a customer. [Skimming the company] website isn't enough; go deeper."

"To show that you're well-versed on the company and its offerings, come up with one great suggestion for how they can improve or a new feature you would add," adds Tarek Pertew, cofounder, Wakefield Media, which provides a content platform and produces Uncubed, a startup hiring event. "It shows you care about the company and have put a lot of thought into it. Also, always send a follow-up email, but try to add value and personalize it rather than just to check in."

3. Know or learn the right technical skills. "Make sure you are concentrating on current and marketable skills," suggests Esther Shih, head of U.S. HR and Operations at Mirantis, a pure play OpenStack company. "Commonly sought skills include programming in Python, PhP, C, Java, JavaScript, Ruby and Perl. Understanding databases based on both SQL (such as MySQL, Oracle and DB2) and NoSQL (such as MongoDB, Cassandra [and] Couchbase) is also key. Skills that set you apart might include understanding Linux internals, or working in a data center to gain hands-on networking and storage experience."

"The job market, especially in IT, is becoming increasingly specialized," says Matt Sigelman, CEO, Burning Glass. "Students who can match their portfolio of skills specifically with what employers are looking for will have an easier time gaining employment," he says. "Based on analytics from Burning Glass, big data skills such as Hadoop and data management, scripting languages such as Python and Perl, and skills that bridge software development with other fields such as graphical user design are among those skills employers find hardest to recruit for."

4. Hone your "soft" skills. "[Soft skills] are nontechnical, interpersonal skills, like effective communication, strong teamwork, leadership, problem solving and negotiation skills," explains Abhijit Pansare, head of recruitment at Collabera, an IT staffing and services company. "Even if you have proficiencies in a hard- to-find technical skill like Java, those skills alone won't land you a job in IT. It's these soft skills that will make you more employable and well- rounded to a potential boss," he says. "Identify the skills where you may not be strongest and invest in improving them. The best way to do this is with practice. Network as much as possible and take as many interviewing opportunities as you can."

"Coming directly out of college, I am hiring for intellect and attitude rather than expertise," says Patrick McGuinness, CIO, Global Risk and Compliance, GE Capital. "I want to see that you understand your context and that you are educated about GE Capital -- what we do and how we use technology in innovative ways for our clients."

So in addition to technical skills, or aptitude, grads looking for a hiring advantage, or who want to get on the management track, should have solid research, communication and listening skills.

5. Gain practical experience in your discipline. "One of the best ways for college seniors to improve their job prospects is by building relevant experience with an internship," says Sigelman. "Internships help job seekers develop and demonstrate the specific skills employers are demanding, and serve as key stepping stones to full-time employment," he explains.

"This is especially true in IT, where internships constitute 13 percent of all postings calling for IT-related skills, which is greater than all other skill areas besides engineering. Moreover, in the past 12 months IT internships were the second-most demanded, with employers seeking interns who already possess expertise in multiple IT skills such as JAVA, C++, and Python," Sigelman says. "For graduates without internship experience, a strong portfolio is another way to demonstrate relevant skills and experience."

"Community service projects are another excellent way to achieve real-world know-how," says Mary Dobransky, dean of the College of Science and Technology at Bellevue University. "Look in your local community for organizations that need help designing a Web page, creating a mobile app, or setting up a network, and volunteer your services."

"Look for programs [or internships that offer] hands-on training," adds Anjul Bhambhri, vice president of Big Data at IBM. "The best way to learn and prepare for a job in IT is to train in real-world scenarios using the systems employed in the business world today," she says. "So it's important that soon-to-be graduates take steps to gain hands-on training before applying for a position. For example, San Jose State University offers an Advanced Certificate in Business Analytics from the Lucas Graduate School of Business. The program incorporates IBM software and project-based collaboration with IBM big data and analytics clients."

6. Showcase your work, or at least your knowledge. "Set yourself apart with a sample of your work, whether it is from an internship or a class project," says Rutt. "Create a SlideShare, blog post or YouTube video of what you have done and how it would be relevant to the position you are applying to. (You can see a great example of an intern from Khan Academy's work here.)"

"As a recruiter, reviewing an applicant's website or portfolio is a great way for me to get a better understanding of who they are," explains Brian Long, talent advocate, The Nerdery, a developer-driven interactive production company. "Create a blog where you can write about things you are learning or trying, your thoughts on the newest JavaScript framework, or the process you went through for a class project."

"Build a digital presence on industry-specific websites, such as GitHub, Quora [or] Stack Overflow," suggests Pertew. "GitHub will allow you to show off the projects you have already worked on and Quora and Stack Overflow can help you exhibit your knowledge by answering other's questions (and asking your own)," he explains. "Recruiters are looking beyond the resume for knowledge, and will often look to GitHub or Quora for potential applicants."

"Demonstrate [your knowledge] by citing examples of how you've jumped in, tackled tasks and been successful," says Michael Waclawiczek, vice president of marketing and operations for distributed database startup NuoDB. "At software startups, a can-do attitude is a quintessential and necessary talent," he explains. Similarly, "demonstrate your ability to lead and take calculated risks. With concrete examples from your personal or professional life, show your strong desire to succeed" -- and how you are will go the extra mile to do so.

Finally, be sure to have a LinkedIn profile, so prospective employers can easily find you -- and you can find and network with prospective employers.

7. Network: Find a mentor or become part of a tech community. "Create a strong network of affiliations, including classmates, faculty and professionals in your discipline," says Dobransky. "Attend meetings held by professional organizations, such as AITP, IEEE and ISACA. These meetings are a terrific way to network with people in your field and learn about potential positions," she says. Then, when looking or applying for tech jobs, "prepare a concise message that describes the type of position you are looking for, and take every opportunity to share your message with your contacts."

"Take advantage of your student alumni network, professors, career center, volunteer opportunities and other community affiliations," agrees Josie Perez, senior vice president, Human Resources, Narus, a cybersecurity solution provider. "Attend industry events to make connections with people. Even if the connections you make now don't lead to a job right away, they may be useful in the future."

"Even if your professors aren't cofounders of a tech company like I am, they are often connected to employers looking for grads," says Giovanni Vigna, a professor at University of California, Santa Barbara, and the cofounder and CTO of Lastline, which develops software that protects against malware.

"Whether the hiring manager is an alum or the hiring company is their former employer, your computer science professors are more hip to the IT job scene than you think," Vigna says.

"Connect to them on LinkedIn and keep their email addresses. They will be a resource for years, and who knows, perhaps they'll invite you to speak to future classes about launching a successful career in IT, or will refer a candidate to you, years from now," Vigna says.

"Find a mentor," says Jesper Helt, chief human resources officer, CommVault, a provider of enterprise backup and recovery, data management, data deduplication, data protection, archiving and eDiscovery software. "Having a mentor who is knowledgeable in the field of study you wish to pursue is imperative. This allows you insights into what your future roles will entail and help you grasp the concepts of the materials in a new light, beyond the walls of the classroom," he says.

"Mentors include professors, advisors and even other students with experience in the field," Helt says. "They are there to inspire you and bring out your confidence in the subject matter, are aware of new trends and future predictions and in the job hunt are a more important resource than just a resume."

8. Participate in local industry events, like hackathons and coding competitions. "We search for talent at tech-related events and competitions like hackathons," says Dorie Blesoff, chief people officer, kCura, which develops Web-based e-discovery applications. "It's a chance for students to demonstrate their skills while networking with peers and potential employers. Recently we hosted the National Day of Civic Hacking at our office, which aimed to solve local organizations' challenges with technology," she says.

"There are also great organizations like the Illinois Technology Association, which convenes Midwestern college students each year for a programming skills tournament, giving students an opportunity to engage with great tech companies," Blesoff says.

"For engineers, participation in coding competitions is also a good way to make your programming skills stand out," says Mike Jennings, senior director of IT at LinkedIn. "Highlight them on your LinkedIn profile [blog, or website] with clear and concise descriptions. Consider competing on sites such as TopCoder."

9. Tailor your resume to each position -- and avoid jargon and simply listing keywords. "Develop a resume that reflects the IT professional you want to be by detailing every project you've completed or been a part of, regardless of its size or scope (even that college coursework demonstrates your skills)," says Jennifer Doran, consultant program manager TEKsystems, an IT staffing firm.

"When writing your resume, make sure the content is detail- oriented and focuses on the skills you've applied, technologies you've worked and, especially important, the results you've generated," Doran says. "Too often I see resumes with a skills summary section that's simply keywords with no details about those skills within the candidate's job descriptions."

10. Don't just apply to the cool startup in Silicon Valley. "Don't be afraid to make your search wide-ranging, not only geographically but in the kinds of things you might like to work on," says Stephen Pimentel, technologist evangelist at database software startup FoundationDB, a data storage technology provider. "Look for companies solving difficult, interesting problems."

"Job seekers in IT fields should look beyond the technology industry as sources of employment," adds Sigelman. "Over half of all job postings for IT roles are outside of the IT sector, in areas such as manufacturing, healthcare, finance and retail."

11. Know your interviewer. "Prior to an interview, ask with whom you will be meeting and use LinkedIn and the Web to learn as much as you can about them," says Doran. "This shows initiative and provides an opportunity to identify similarities you might share with your interviewer (e.g., attended the same college or played the same sport).

The most positive feedback from hiring managers comes when a candidate is able to make a personal connection," Doran says. "Also, take note of the professional paths of the IT managers with whom you interview. Asking how they got to where they are today is an excellent icebreaker and shows career initiative."

12. Finally, be realistic about salary. "Be realistic and don't expect that you are going to get $100K+ because that's what you saw that job position pays at the high range," says Brad Roth, IT manager, EZSolutionIT, which provides computer and IT services. "That high range is meant for people that have years of experience in the field."
